ROTARY STAMPING DEVICE.

To all whom it may concern:

. Be it known that I, CHARLES DIMEGH, a citizen of the United States,residing at West Point, in the county of Orange, State of New York, haveinvented a new and useful Rotary Stamping Device; and I do here- 4 bydeclare the following to be a full, clear,

- e bya number of printing surfaces, such as and eXact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.-

The present invention relates to a rotary stamping device, and has forits object to provide a device of this characterwhich embodies novelfeatures of construction whererubber stamps, can be mounted upon theperiphery of a drum and any selected one of the printing surfacesquickly inked and brought into proper position for stamping. Furtherobjects of the invention are to provide a" rotary stamping device-whichis simple and inexpensive in its construction,

which admitsof the printing surfaces being quickly changed, which isvery compact in its design, and which can be, used without danger ofsoiling the fingers.

With these and other objects in View, the invention consists in certainnovel combinations and arrangements of the parts as will more fullyappear as the description proceeds, thenovel' features thereof beingpointed out in the appended claims.

For a full understanding of the invention, reference is to be had to thefollowing description and accompanying drawing, in

which Figure 1 is a side elevation of a rotary stamping deviceconstructed in accordance with the invention, the stamping drum andindicating pointer being shown in their normal positions. Fig. 2 is aview similar to Fig. 1, showing the indicating'pointer in thepositionassumed preparatory to rotat Specification of Letters Patent.

ment of the invention, the numeral 1 designates a stamping base which isprovided at one end thereof with a standard 2. Correspending levers 3are pivotally mounted at points spaced from the rear ends thereof, asindlcated at 4, upon opposite sides of the standard 2. 'lhe rear endsofthe levers 8 are connected to springs 5 which normally tend to swingthe forward ends of the levers upward and lift the printing drum awayfrom the stamping base 1. The extremities of the levers 3 are extendeddownwardly at 3 and connected by a shaft 7 which has the printing drum 6rigidly mounted thereon.

A fork 8 straddles the printing drum 6 and has the arms thereofpivotally mounted upon the shaft 7, the arched end of the fork beingprovided with a handle 9, while the arms thereof terminate at their freeends in resilient pointers 10 which are used to inclicate which one ofthe printing surfaces on the periphery of the drum is in operativeposition. One end of the shaft 7 terminates in a wing or finger piece 11by means of which the shaft and drum can be rotated to bring anyselected one of the printing surfaces into operative position. Theopposite end of the shaft 7'ter1ninates in a head 1.2, and a spring 13is interposed between the said head and the adjacent lever 3, therebycausing the ends of the printing drum 6 to be frictionally gripped bythe fork ,8. By grasping the handle 9 of the fork 8 and forciblyrotating the printing drum 6 through the medium of the finger piece 11,any selected one of the printing surfaces on the periphery of the drumcan be brought into operative position, and the frictional engagementbetween the fork and the drum is ordinarily sufficient to hold the partsagainst accidental displacement.

The periphery of the printing drum 6 is provided with a series oflongitudinally extending undercut or dovetail grooves or recesses 14.Correspondingly shaped sheet metal clips 15 are adapted to be slippedremovably into the recesses 14, and these clips 15 are designed to carryblocks 16 upon which the printing surfaces 17 are mounted. These blocks16 are interchangeable and removable, so that the printing surfacescarried by the drum 6 can be changed as often as desired. One end of thedrum may be provided with a pair of spaced projections or knobs 18opposite the base of each of the dove-tail recesses 14. The resilientpointer 10 of the fork 8 will ride over the projections 18 when the drum6 is forcibly rotated through the medium of the finger piece 11,although when any particular one of the printing surfaces is broughtinto operative position, the spring pointer will seat itself between thecorresponding pair of projections 18, thereby locking the fork and drumagainst relative rotation.

An inking roller 19 is journaled between a pair of arms 20 which projectforwardly from the upper end of the standard 2, and the springs 5normally operate upon the levers 3 to swing the printing drum 6 upwardlytoward theinking roller.

Then it is desired to use the stamp, a selected one of the printingsurfaces 17 is rotated into position opposite the pointers 10 of thefork S. The handle 9 is then swung downwardly and forwardly to bring theprinting surface into engagement with the inking roller 19, after whichthe handle 9 is swung upwardly to bring the fork 8 into a substantiallyvertical position with the selected printing surface properly inked andatthe bottom of the printing drum. The paperor article to be stamped maybe inserted between the drum 6 and base 1, and

' the printing surface brought into engagem'ent therewithby pressingdownwardly on the handle 9. As soon as this pressure upon the handle 9is released, the springs 13 will again lift the printing drum intoinoperative position, whereupon the paper or other article which wasstamped can be removed. This operation can be very quickly repeated, asoften as desired, and it .will be obvious that any desired one of theprinting surfaces 17 can be very readily brought into proper positionfor use. If desired, the pointers 10 may carry counter-weights 21 forcausing the fork 8 to automatically as sume an upright or verticalposition as soon as released.

Having thus described the invention, what I claim as new and desire tosecure by Letters Patent, is

1'. A rotary stamping device, including a base plate, a standard, apairof levers pivotally mounted upon the standard, a printing drumjournaled between the levers, a series of independent printing surfacesmounted on the periphery of the drum, a fork straddling the drum andadapted to grip the ends thereof at adjusted positions, ahandle on thefork for swinging the printing drum toward the base plate, and inkingmeans.
